I tried to replace the CXTSplitterWnd::ShowRow() and CXTSplitterWnd::HideRow() methods in the XTP 1030
with the same methods in the XTP 9.7.
I recompiled XTP 1030 project and the pb is fixed...


If it can help, here is the 1030 and 9.7 code for these methods:

1030 :
====

void CXTSplitterWnd::ShowRow()
{
    ASSERT_VALID(this);
    if (m_nRows == m_nMaxRows && m_nHiddenRow == -1)
    {
        return;
    }
    ASSERT(m_nHiddenRow != -1);

    int nShowRow = m_nHiddenRow;
    m_nHiddenRow = -1;

    int cyNew = m_pRowInfo[m_nRows].nCurSize;
    m_nRows++;  // add a nRow

    ASSERT(m_nRows == m_nMaxRows);

    int nRow;

    // Show the hidden nRow
    int nCol;
    for (nCol = 0; nCol < m_nCols; ++nCol)
    {
        CWnd* pPaneShow = GetDlgItem(AFX_IDW_PANE_FIRST + m_nRows * 16 + nCol);
        ASSERT(pPaneShow != NULL);
        pPaneShow->ShowWindow(SW_SHOWNA);

        for (nRow = m_nRows - 2; nRow >= nShowRow; --nRow)
        {
            CWnd* pPane = GetPane(nRow, nCol);
            ASSERT(pPane != NULL);
            pPane->SetDlgCtrlID(IdFromRowCol(nRow + 1, nCol));
        }

        pPaneShow->SetDlgCtrlID(IdFromRowCol(nShowRow, nCol));
    }

    // new panes have been created -- recalculate layout
    for (nRow = nShowRow + 1; nRow < m_nRows; nRow++)
        m_pRowInfo[nRow].nIdealSize = m_pRowInfo[nRow - 1].nCurSize;

    m_pRowInfo[nShowRow].nIdealSize = cyNew;
    RecalcLayout();
}

void CXTSplitterWnd::HideRow(int nRowHide)
{
    ASSERT_VALID(this);
    if (m_nHiddenRow != -1)
    {
        // return if the requested one is hidden
        if (m_nHiddenRow == nRowHide)
        {
            return;
        }
        ShowRow();
    }
    ASSERT(m_nRows > 1);
    ASSERT(nRowHide < m_nRows);
    ASSERT(m_nHiddenRow == -1);
    m_nHiddenRow = nRowHide;

    int nActiveRow, nActiveCol;

    // if the nRow has an active window -- change it
    if (GetActivePane(&nActiveRow, &nActiveCol) != NULL)
    {
        if (nActiveRow == nRowHide)
        {
            if (++nActiveRow >= m_nRows)
                nActiveRow = 0;
            SetActivePane(nActiveRow, nActiveCol);
        }
    }

    // hide all nRow panes.
    int nCol;
    for (nCol = 0; nCol < m_nCols; ++nCol)
    {
        CWnd* pPaneHide = GetPane(nRowHide, nCol);
        ASSERT(pPaneHide != NULL);

        pPaneHide->ShowWindow(SW_HIDE);
        pPaneHide->SetDlgCtrlID(AFX_IDW_PANE_FIRST + m_nRows * 16 + nCol);

        int nRow;

        {
            CWnd* pPane = GetPane(nRow, nCol);
            ASSERT(pPane != NULL);

            pPane->SetDlgCtrlID(IdFromRowCol(nRow-1, nCol));
        }
    }

    m_nRows--;
    m_pRowInfo[m_nRows].nCurSize = m_pRowInfo[nRowHide].nCurSize;

Hello,


I was using a CXTSplitterWnd in my App with
the XTP 9.7 and all worked fine.
I'm now using the 1030 and my App crashes if:

I hide the 1st row
I hide the 1st column
I show the 1st row
I show the 1st column => Assert in :

BOOL CWnd::ShowWindow(int nCmdShow)
{
    ASSERT(::IsWindow(m_hWnd) || (m_pCtrlSite != NULL));

    if (m_pCtrlSite == NULL)
        return ::ShowWindow(m_hWnd, nCmdShow);
    else
        return m_pCtrlSite->ShowWindow(nCmdShow);
}


I tried with the SplitterWindow sample and I get the same pb!!


The code has been modified in the CXTSplitterWnd::ShowRow()
method since the 9.7 version...  any idea?

Thanks.
